You don't work merely for your own survival under capitalism, most of your labor goes to supporting the capitalist class (and bombing foreigners to keep resources cheap so those capitalists can make even more money).

Half a century ago, working in a grocery store was enough to buy a home, raise a family, and put a kid through college. The job did not get less productive, if anything each worker produces more than ever with automation, but a greater share goes to the capitalist class, both through stagnant wages and increasing costs.
